I'm a new Linux Mint user and don't know much about command prompts, codes, or anything like that. I recently learned the "ctrl+alt+backspace" shortcut which was great. So my screen froze at one point so I thought I could just press that shortcut like 4-5 times (don't judge me I'm new) so it would clear and I could go back to the desktop BUT I can't. I'm not even sure what to do but I assume I'm able to fix this issue with a command?

Here's what it says:

Your session only lasted less than 10 seconds. If you have not logged out yourself, this could mean that there is some installation problem or that you may be out of disk space. Try logging in one of the failsafe sessions to see if you can fix the problem.

No, it doesn't freeze much. I think I might have someone listening on my sessions though, I just don't know how. You mind me asking what that command does? Definitely won't be keying in any random command.
